Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a dispenser cosmetic stick container.

[Conventional technology]

Conventionally, cosmetic stick containers have consisted of a holding tube that holds cosmetic sticks such as lipstick, a guide tube with a guide groove that engages the holding tube so that it can slide up and down without rotating, and a guide tube that allows the holding tube to slide up and down. The main components are: a spiral tube with a spiral groove, a sleeve in which the cosmetic stick is stored, an outer tube that covers these structures, and an inner tube that locks the lid, which is often used for design purposes, to the container. It was a series of components, with springs, bottom covers, and other additions depending on their function.

[The problem that the idea aims to solve]

Although this configuration has been used for many years and has resulted in a highly reliable and functionally excellent container, it also has the drawbacks of being heavy and increasing manufacturing costs. In view of the above points, the applicant has decided to
In Publication No. 58-46515, the number of parts is reduced,
We are proposing a cosmetic stick container that is lightweight and can be manufactured at low manufacturing cost.

However, in the configuration of this invention, an annular concave groove is carved in the lower part of the threaded rod, and a concave bead is provided around the outer wall of the sleeve so that the inner wall protrudes, and this part can be freely rotated into the concave groove. However, since they are engaged in a way that cannot be removed, a gap C as shown in Fig. 3 is created between the concave groove and the inner wall of the concave bead, resulting in vertical looseness between the sleeve and the threaded rod. This caused not only discomfort to the user but also difficulty in obtaining a good operating feeling.

[Means to solve the problem]

A holding cylinder 2 that fits and holds the decorative stick 1 has a lower cylinder 5 hanging thereon, which has a threaded piece 3 on its inner wall and a protrusion 4 on its outer wall. A sleeve 15 that accommodates the holding cylinder 2 in a vertically slidable manner has a protrusion 4 on the side wall of the lower cylinder 5.
A guide groove 16 is formed in the vertical direction through which the holding cylinder 2 is guided in a non-rotatable manner, and a concave bead 1 is formed on the outer wall at the lower end
The inner wall is made to protrude by providing 7 around the circumference. Threaded rod 6 inserted from below into the lower cylinder 5 of the holding cylinder 2
is a threaded groove 7 into which the threaded piece 3 of the lower cylinder 5 is threaded into the outer wall.
A concave groove 9 that rotatably engages with the inner wall of the concave bead 17 of the sleeve 15 is provided around the part exposed from the lower cylinder 5 below the screw groove 7, and further below the concave groove 9. A flange portion 10 is provided. The outer cylinder 14 that covers the lower part of the sleeve 15 is connected to the threaded rod 6.
Insert and fix the flange portion 10 of. In the above configuration, an O-ring 8 is disposed in a gap C formed between the concave groove 9 of the threaded rod 6 and the inner wall of the concave bead 17 of the sleeve 15 engaged with the concave groove 9. It is elastically brought into sliding contact with the inner wall surfaces of the concave groove 9 and the concave bead 17.

[Effect]

Since the present invention has the above configuration, the lid body 11 is removed and
When the outer cylinder 14 is held and the sleeve 15 is rotated, the protrusion 4 protruding from the outer wall of the lower cylinder 5 below the holding cylinder 2 engages with the guide groove 16 formed in the sleeve 15. Therefore, it rotates together with the sleeve 15,
The threaded rod 6 to which the screwing piece 3 of the lower cylinder 5 is screwed does not rotate because the flange portion 10 is fixed to the outer cylinder 14, and the screwing piece 3 that rotates does not rotate. Since it is screwed together, the holding cylinder 2, that is, the cosmetic stick 1, moves up and down by the screwing action.

At this time, the concave groove 9 of the threaded rod 6 and the sleeve 15
Since the O-rings 8 are installed so as to slide in the gaps C formed by the engagement of the inner walls of the concave beads 17, it is possible to absorb rattling during operation and provide a comfortable operating feeling.

〔Example〕

A holding tube 2 that fits and holds the decorative stick 1 has a lower tube 5 hanging down from its lower end. A screwing piece 3 is provided to protrude from the inner wall at the lower end of the lower cylinder 5, and a protrusion 4 is provided from the outer wall at the lower end. The holding cylinder 2 is slidably housed inside the sleeve 15. A guide groove 16 is vertically bored in the side wall of the sleeve 15, through which the protrusion 4 of the lower cylinder 5 passes, and guides the holding cylinder 2 in a non-rotatable manner. Below this guide groove 10, a concave bead 17 is provided around the outer wall and projects toward the inner wall. Further, a threaded rod 6 is inserted into the lower cylinder 5 from below. A threaded groove 7 is screwed into the outer wall of the threaded rod 6 to be threaded into the threaded engagement piece 3 of the lower cylinder 5. A concave groove 9 is provided on the side wall below the threaded groove 7 and below the lower cylinder 5 so that the inner wall of the concave bead 17 of the sleeve 15 is rotatably engaged therewith. A gap C is provided in the area where the concave groove 9 and the concave bead 17 engage, and an O-ring 8 molded from an elastic material such as nitrile butadilene rubber is inserted into this gap C. There is. This O-ring 8 is connected to the inner wall of the concave groove 9 and the concave bead 17.
It is in sliding contact with each of the inner walls. Also, the threaded rod 6
A flange portion 10 is provided below the concave groove 9 . This flange portion 10 is inserted and fixed to the lower part of the outer cylinder 14. This outer cylinder 14 has a lid 1 at its upper end.
A middle cylinder 13 having a protruding dowel 12 into which a dowel 1 is removably fitted is fastened.

Next, the assembly of the embodiment of the present invention will be explained. Screw and insert the threaded rod 6 into the lower cylinder 5 of the holding cylinder 2,
At the same time as the holding cylinder 2 is inserted into the sleeve 15, the protrusion 4 of the lower cylinder 5 is engaged with the guide groove 16, and the inner wall of the sleeve 15 is made to protrude by forming a concave bead 17 on the lower outer wall of the sleeve 15, By engaging the concave groove 9, the sleeve 15 and the threaded rod 6
The flange portion 10 of the threaded rod 6 is inserted and fixed into the outer cylinder 14 to which the inner cylinder 13 has been fixed in advance to form a completed product.

[Effect of idea]

With the above configuration, the present invention eliminates the need for a guide tube with a guide groove, which was conventionally necessary, by forming a guide groove 16 in the thin-walled metal sleeve 15, thereby reducing weight. Moreover, the assembly process is also simple. Furthermore, during the assembly process, check the feeling of feeding operation.
This can be done in the assembled state before they are fixed to the outer cylinder 14, that is, when the threaded rod 6, the holding cylinder 2, and the sleeve 15 are assembled, respectively. Therefore, unlike conventional containers, if the outer cylinder 14 and the inner cylinder 13, which have been subjected to expensive surface treatment, are assembled in order to give an elegant design, it is difficult to assemble the container and the operation of the container will not feel normal. If it is not possible to judge and the feeling of operation is abnormal, the outer cylinder
Also, it is possible to prevent the middle cylinder 13 from being wasted as expensive scrap material.

Further, an elastic O-ring 8 is inserted into a gap C generated between the concave groove 9 of the threaded rod 6 and the inner wall of the concave bead 17 of the sleeve 15, and has elasticity so as to be in sliding contact with each other. This prevents the uncomfortable rattling of the sleeve 15 during the feeding operation, and reduces O.
The sliding resistance of the ring 8 makes it possible to adjust the rotation operation feeling to be favorable.
